DNG is washed out with very low contrast!

[Wolfgang]

Hi,

I just updated from Beta 8 to Beta 11 and now when I export as DNG and then import into Lightroom Classic or Photoshop, the images look terrible with very low contrast and totally washed out!

Please help!

Thank you.

Could you provide an example DNG for download? Best with the project
file you used to create it. Use wetransfer, dropbox or similar.

Out of interest, I tried generating some sample images of my own to dng format using PTGui V13 beta 11 and confirmed that they do look somewhat different from jpeg versions, when opened in Photoshop CS6 (on Windows 11).  However, the differences were not huge.   OTOH, the differences when opened in Affinity Photo V1 were considerably more stark:

I also tried converting the dng images with the free NCH Photopad Image Editor and got exactly the same result.  (Probably using the same raw converter).

Yes, differences are to be expected. DNGs need to be developed into an
image. This is a subjective process and all raw converters do this
differently and there's a lot to tune.

But if the result is 'very low contrast and totally washed out' (quoting
Wolfgang) then I would like to investigate.

Kind regards,

Sorry for the delay! I was hoping Beta 12 would fixed this. Alas it is still Beta 11 for the time being.

Anyway I have uploaded everything - original DNG files, Project file, Stitched files from both Beta 8 and Beta 11.

You will see Beta 11 looks horrible! While Beta 8 looks gorgeous!

Here is the link to the shared Google Drive folder:-

Thank you!

Also, I would like to point out that this problem does not exist if I export as TIFF 16 bit. So this is my temporary workaround.

And yes, I am very familiar with RAW files of all shapes and forms. Moreover, I comparing the RAW/DNG outputs from Beta 8 to Beta 11! Nothing else has changed! My workflow is exactly the same! So please have a look at what I have uploaded and investigate.

Thank you!

P.S. I never updated to Beta 9 or 10. So all I am do is compare my old results from Beta 8 to the newly updated Beta 11. Thanks again!

This should be fixed in PTGui 13 beta 12.

Many thanks.
